Impact of intermittent renewable energy generation penetration on the power system networks – A review

Entrance of intermittent renewable power energy sources has brought in benefits mainly associated with emission reduction to help the climate change cause and reduce pollution. However, entrance generation sources, wind solar that are by nature not come without its own challenges. Future grids will see continued elevation instantaneous penetration levels may potentially be as high 100% for some periods. This paper reviews published works highlights technical challenges require further research ensure dominated inverter-based or purely powered continue operate reliably remain stable all operating scenarios. The outlines opportunities areas sytem security assessment, voltage frequency management, system stability, resource forecasting techniques unit commitment, behind meter generators loads integration grid, support, flexibility assessment methods, protection schemes enhancement, quality mitigation modelling requirements support real-time operation.
